* doc/tm.texi (TARGET_PROMOTE_FUNCTION_MODE): Add documentation
for for_return == 2.
* function.c (assign_parm_setup_reg): Use for_return == 2, improve
comments.
* calls.c (expand_call): Fix typo.
* explow.c (promote_decl_mode): Use for_return == 2 for RESULT_DECL
and PARM_DECL.
* stmt.c (expand_value_return): Use promote_function_mode to copy out
of pseudo.
* targhooks.c (default_promote_function_mode): Handle for_return == 2.
* config/cris/cris.c (cris_promote_function_mode): Likewise.
* config/mmix/mmix.c (mmix_promote_function_mode): Likewise.
* config/pa/pa.c (pa_promote_function_mode): Likewise.
